No decisions have been made regarding a special election to replace former state Rep. David Sullivan.

Brian McNiff, spokesman for the office of Massachusetts Secretary of State William Galvin, said to his knowledge there have been no discussions held between that office and that of House Speaker Robert DeLeo. A spokesman in DeLeo’s office referred questions to the secretary of state’s office.

Sullivan, of Fall River, officially resigned his seat as the 6th Bristol district representative at 5 p.m. Sunday to become the executive director of the Fall River Housing Authority. Sullivan started his new position Monday morning.

Three Democratic candidates, David Dennis, Carole Fiola and Bradford Kilby, have voiced their interest in running for the seat. No Republicans have publicly declared a potential run.

The 6th Bristol district covers most of Fall River’s northern half and the west side of Freetown.
